你好朋友我已经创建了wpf主题，其中我放置按钮所以我的问题是当我点击特定按钮时，完整的应用程序颜色应该在下面更改我的代码和xaml。

public UCUserThemes()
{
InitializeComponent();
}
private void lstboxWindowsTransparency_SelectedIndexChanged(object sender, RoutedEventArgs e)
{
DXSplashScreen.Show<WaitDialogSSView>();
DevExpress.Xpf.Core.ThemeManager.ApplicationThemeName = DevExpress.Xpf.Core.Theme.Default.ToString();
ImageSource img = new BitmapImage(((DevExpress.Xpf.Core.Theme)lstboxwindowsTransparancy.SelectedItem).SmallGlyph);
ThemeManager.ApplicationThemeName = Theme.Office2010BlackFullName;
DXSplashScreen.Close();
}
}
}
答案 0 :(得分：1)
ThemeManager.ApplicationThemeName= "Your Theme";
